[AH] home-built doepfer case?

hi. i'm planning to get a doepfer system soon, something small which can be
expanded gradually.
the largest chunk of case seems to be for the case. i would like to build my
own case, out of wood, for the system. i'm quite handy with the power tools,
but i've never built a power supply etc....
the a-100mps mini power supply can power 4 modules, and is only 80.00.
i could buy 6-8 modules and 2 of these, and save a nice chunk of change. but
are they sufficient? is there anything else i need, or would it simply be
CASE=MINI POWER SUPPLIES=MODULES?
any and all info would be greatly appreciated.
thanks, a lot...
